The 3R26-271 solves all three: it is machined specifically for 2.750″ OD / 0.065″ wall steel tube, uses the 3R series u-joint interface, and provides a 1.750″” center-to-weld dimension that fits standard driveshaft geometry for driveshaft vehicles.Dimensional DataDimensionValuePart Number3R26-271Series3R (cap –)Butt Diameter2.625″Tube OD × Wall2.750X0.065″Ctr UJ to Weld1.750″”MaterialSTEELConstruction & ReliabilityHeat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load.

This weld yoke is compatible with any shaft built to that series standard. Confirm the following before installation:Tube OD is 3.000″ — measure with calipers, not a ruler.Tube wall is 0.065″ — thinner walls require reduced heat input to avoid burn-through.Companion u-joint is a 3R series cross.Companion yoke or flange at the opposite end is also 3R series.Post-Weld Quality CheckInspect the weld toe for undercut and lack-of-fusion defects. Rotate the shaft in V-blocks and measure TIR at the u-joint seat; values above 0.005″ require correction before dynamic balancing. Balance the completed assembly per your vehicle’s balance spec — typically 0.20-0.25 oz-in for passenger car applications, tighter for performance builds.

The 1226-25 solves all three: it is machined specifically for 2.500″ OD / 0.065″ wall steel tube, uses the 1251 series u-joint interface, and provides a 1.750″” center-to-weld dimension that fits standard driveshaft geometry for light-duty import and compact truck vehicles.Dimensional DataDimensionValuePart Number1226-25Series1251 (cap 1.062″)Butt Diameter2.375″Tube OD × Wall2.500X0.065″Ctr UJ to Weld1.750″”MaterialSTEELNotesFOREIGNConstruction & ReliabilityHeat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load.

The 1226-26 weld yoke delivers a precision-bored butt diameter of 2.400″” to match standard 2.550″ OD tubing at 0.080″ wall thickness, giving you a tight-fitting joint that welds cleanly and balances predictably.Key Specifications at a GlanceParameterDetailSKU / Part Number1226-26U-Joint Series1251Butt Diameter2.400″”Compatible Tube (OD x Wall)2.550X0.080″Center UJ to Weld Face1.750″”ConstructionSTEELManufacturerUDSSpecial NotesFOREIGNWhy the Tube-to-Yoke Fit MattersA properly fitted weld yoke eliminates weld gap variation that causes runout after cooling.Full-penetration welds require consistent clearance — ideally 0.003-0.005″ radial gap.Insufficient tube wall engagement reduces fatigue life under torsional cycling.This yoke’s bore is held to close machining tolerance for repeatable fitment.Material PerformanceHeat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load. The 1251 series designation ensures this yoke is dimensionally matched to standard 1251 u-joint crosses — no shimming or adapting required.Ordering & Pairing GuidanceOrder this yoke alongside a matching 1251 series u-joint cross and the appropriate companion flange or slip yoke for your specific driveshaft layout. Confirm your tube OD and wall before placing the order — substituting a different tube size will result in a loose or interference fit that compromises weld quality and structural integrity.FOREIGN Show less (-) | Brand: UDS Butt Dia: 2.400" Center U-J to Weld: 1.750" | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

With a butt diameter of 2.375″ and tube compatibility of 2.500X0.065, this component integrates directly into custom or OEM-spec propshaft builds.

When pairing this weld yoke with a u-joint, verify that both components share the same series designation to ensure proper cap pocket engagement and retention clip compatibility.Tube FitmentThis yoke is manufactured to accept tubing with an outside diameter of 2.500″ and a wall thickness of 0.065″. Before welding, confirm that the tube OD matches the butt bore precisely. A gap exceeding 0.005″ between tube and yoke bore can introduce weld porosity and reduce joint fatigue life. Use a V-groove or fillet weld with full penetration; partial welds are not acceptable for rotating driveshaft components.Material & FinishHeat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load.Material: STEELWeld prep: machined to close tolerance for consistent gapBalance: suitable for dynamic balancing post-weldSurface: raw machined; paint or coat as required for corrosion protectionInstallation NotesAlign the yoke ears parallel to the mating yoke ears before tacking. Weld in a balanced sequence (opposing passes) to minimize heat distortion. After welding, re-check runout — total indicator reading (TIR) should be under 0.005″ at the u-joint seat. Dynamic balance the completed assembly to OEM specifications before installation.Note: FOREIGN – HONDA Show less (-) | Brand: UDS Butt Dia: 2.375 Center U-J to Weld: 1.375 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The 1.571″ butt diameter is bored to accept 1.750″ OD tubing at 0.095″ wall, providing the controlled clearance needed for a full-penetration circumferential weld. The 1.688″ center-to-weld dimension aligns with industry-standard 1300 driveshaft geometry used on light truck and performance car vehicles.Complete DimensionsSpecificationValuePart Number3026-17U-Joint Series1300Butt Diameter1.571″Tube OD × Wall1.750X0.095″Center UJ to Weld1.688″MaterialSTEELBrandUDSWhy Material Choice Matters at the Weld JointHeat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load. The yoke ears are machined to series-standard cap pocket dimensions — the 1300 series uses a 1.062″ cap diameter — ensuring that standard u-joint crosses seat flush with no shimming.Application & Fitment GuidanceThe 1300 series is the standard u-joint specification for light truck and performance car driveshaft applications. This weld yoke is compatible with any shaft built to that series standard. Confirm the following before installation:Tube OD is 1.750″ — measure with calipers, not a ruler.Tube wall is 0.095″ — thinner walls require reduced heat input to avoid burn-through.Companion u-joint is a 1300 series cross.Companion yoke or flange at the opposite end is also 1300 series.Post-Weld Quality CheckInspect the weld toe for undercut and lack-of-fusion defects. Rotate the shaft in V-blocks and measure TIR at the u-joint seat; values above 0.005″ require correction before dynamic balancing. Balance the completed assembly per your vehicle’s balance spec — typically 0.20-0.25 oz-in for passenger car applications, tighter for performance builds.

Butt diameter is 1.813″, center u-joint to weld face is 1.688″. Material is steel. It ships machined and ready to weld — no cleanup bore required.Spec SheetFieldSpecPart No.3026-20UJ Series1300Butt Dia.1.813″Tube (OD x Wall)2.000X0.095″Ctr-UJ to Weld1.688″MaterialSTEELBrandUDSTube Compatibility CheckThe bore is machined for 2.000″ OD tube at 0.095″ wall. Using a different tube OD — even 0.020″ off — will cause a loose fit that traps weld gas and weakens the joint. If your tubing is metric or slightly non-standard, measure with calipers before ordering.Series InterfaceThe 1300 series u-joint pockets match standard 1.062″ cap-diameter crosses used in light truck and performance car drivetrain applications. Using a different series yoke at the other end of the shaft is fine as long as the mating u-joint is also a cross-series design — but keep both ends consistent when possible for balanced angularity.Welding & BalancingHeat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load. After welding, spin-balance the shaft assembly to at least 0.25 oz-in residual imbalance per balancing plane — less for high-RPM or highway applications.
